smb.conf manpage says: Example: idmap backend = ldap:ldap://ldapslave.example.com Example: idmap backend = idmap_rid:BUILTIN=1000-1999,DOMNAME=2000-100000000 Example: idmap backend = idmap_ad while winbindd log says: idmap_init: idmap backend uses deprecated 'idmap_' prefix. Please replace 'idmap_ad' by 'ad' in /etc/samba/smb.conf Please update the manpage. Thanks.
Fixed with revision 1214. Thanks for reporting!
